Geotab® GO9® — Expandable Telematics Device

For the most up-to-date version, please visit:

Two Geotab GO9 devices on a white background.

GO9 Device

Geotab’s GO9 telematics device is the most powerful yet. The GO9 offers a 32-bit processor, 4x more memory and 5x more RAM than the GO8®. Similar to the GO8, the GO9 offers state-of-the-art GPS technology, g-force monitoring, GEOTAB IOX® expandability, engine and battery health assessments, and communication on the LTE network (for more information, refer to the Cellular section of the Technical Specifications and Features table below).

Vehicle Tracking

Using Geotab’s patented tracking algorithm, the GO9 accurately recreates vehicle trips and analyzes incidents. The GO9 also offers in-vehicle alerts to instantly notify drivers of infractions and — with hardware Add-Ons — provides live coaching for driver’s on-road performance. The GO9 does not require a dash-mounted antenna or any wire splicing.


GO device security is designed for end-to-end protection of your data.

Key security implementations in the GO9 include:

  1. Network interfaces use authentication, encryption, and message integrity verification.
  2. Each GO9 device is individualized. Each device uses a unique ID and non-static security key — making it difficult to fake a device’s identity.
  3. Over-the-air updates use digitally-signed firmware to verify that updates come from a trusted source.
  4. Geotab uses independent third-party experts to validate the platform from end to end.
  5. A FIPS 140-2 validated firmware module used for performing cryptography (certificate #3371).
